Answer:

Option (4)

Step-by-step explanation:

Given system of equations is,

y = -x²- 4x - 3

y = 2x + 5

To get the solution of the system of equations algebraically,

2x + 5 = -x²- 4x - 3

Now combine like terms onto one side of the equation.

-x² - (4x + 2x) - (3 + 5) = 0

x² + 6x + 8 = 0

Then factorize the equation,

x² + 4x + 2x + 8 = 0

x(x + 4) + 2(x + 4) =0

(x + 2) (x + 4) = 0

x = -2, 4

Option (4) is the answer.

A scale on a hiking map shows that 33 inches represents 1.25miles. What number of inches on the map represent 1010 actual miles?

user100 [1]

Answer:

26,664 inches

Step-by-step explanation:

Set up a proportion to solve this...

33 inches is to 1.25 miles as 'x' inches is to 1,010 miles

33/1.25 = x/1,010 now solve for x by cross multiplying

33,330 = 1.25x

33,330/1.25 = x

26,664 = x
